' Be it known that I, J ULES VANPETEGHEM, a subject of the King of Belgium, and a resident of 14Rue de la Ooriandre, Ghent,Belgium, have invented certain new and useful Devices for Loading Oops on Spindles, of which the following is a specification.

This invention relates to an improvement in preparing bobbins and fixing them in shuttles and is-designed to lessen the labor of the weaver and to preserve his health. At the same time the stoppages of the loom are diminished and its producing capacity is correspondingly increased.

' In the system of working hitherto in use the bobbins are handed to the weaver, who then fixes them in the shuttles. In doing so he must not only properly fix the bobbin in place, but must compress the cop, so as to attain a certain amount of adhesion between the layers of thread, sufficient to enable the bobbin to support without deformation the numerous and violent shocks to which it is submitted during its course through the loom, for such deformation causes bad unwinding and frequently wrecks the bobbin. Accordingly to fix the cop 0n the spindle of the shuttle the workman usually manually forces the cop onto the spindlewith all his force, and as a good weaver is not necessarily a muscular man a large proportion of the bobbins are badly prepared. Again,every time the shuttle has to be refilled or the thread breaks the loom has to be stopped, causing aloss of time, which may amount to from thirty-five to forty per cent. Where there are many wefts. By the present invention this loss of time is much diminished because the faultyunwindin g and consequent breakages are avoided and the shuttles contain nearly twice as much thread as is usually the case, so that stoppages for refilling are reduced. For this purpose the cop is fixed and compressed mechanically on the spindle. When the cop is placed on the spindle, it descends nearly to the bottom thereof. It is then submitted to pressure, which at the same time fixes it on the spindle and compresses it in the direction of the axis of the spindle to such an extent that the shuttlecan contain nearly twice as much thread as was formerly the case.

For facilitating the refilling of the I while Fig. 6 is a special form of spindle, the

purpose of which will be explained.

The shuttle is made in two pieces-that is to say, the spindle is independent of the shuttle, and in order that the former may readily be placed in and removed from the latter it has a notch a at its lower end, which in inserting the bobbin into the shuttle takes over a pin (1, so that the extreme end Z) of the spindle can be introduced between this pin and the spring a. The bobbin is then turned on the pin d until it lies in the shuttle, as is commonly the case. To facilitate the introduction of the end I), the base of the spindle is slopedfas shown at c c, Fig. 1. lVhen the bobbin is placed inthe shuttle, as shown in Fig. 3, it is fixed therein in the manner usually adoptedfor fixing bobbins in shuttles.

The apparatus for fixing and compressing the cops on the spindles is shown in Figs. 4: and 5 and is constructed as follows: A is the frame. B is the starting-lever, carrying the pawlC and centered at B. D is a ratchetwheel keyed to the shaft U and having a part D without teeth. E is alever centered onU and carrying at one end the pawlF and connected at the other endby a link G with a crank ll on a shaft 1, which is intermittently revolved. J is ahollow cone lined with coarse felt or cloth and of an internal angle corresponding with that of the head of the bobbin onto which it is to be placed in order to com press the cop L on the spindle O. K is a sliding piece and carries the -cone J and an arm X. M is a rod attached at its lower end to a crank S on the shaft U and at its upper end to the arm X through the spring N. Q is a spring which serves to raise the lever B. T is a support for the spindle O and is met erably in the form of a clamp, in which the end of the spindle can be held by the screw V. W is the bearing of the shaft U.

As already said, one of the chief advantages 5 of this invention is that the shuttle is made to hold nearly double the quantity of thread held by ordinary shuttles. Vhile this is achieved by compressing the cops, it is obvious that the spindles must have the ordinary length to fit the shuttles. The length of the cop before compression, however, is nearly double that of the spindle, as is represented in dotted lines in Figs. 4; and 5, so that it is necessary to use a temporary spindle nearly double the length of that which is to carry the cop in the shuttle. For this purpose there is fitted over the upper end of the permanent spindle O a socket on the lower end of a supplementary slightly-concd spindle (Shown in dotted lines in Figs. 4 and 5 and on a larger scale in Fig. 6.) The joint spindle O 0' thus produced is the length of the uncompressed cop and is fixed in the support T by means of the notch a in the permanent spindle O and by means of the screw V. This mode of temporarily lengthening the spindle is only one of several.

The apparatus works as follows: The shaft I rotates intermittently and oscillates the lever E 011 the shaft U. \Vhen the pawl F, carried by the upper end of lever E, is resting on the part I) of the ratchet-wheel l), the oscillation of the lever E has no effect upon the said ratchet. Fig. '-L therefore shows the apparatus at rest. To put it into action, the lever B must be depressed, so that the pawl C may turn the ratchet-wheel D in the direction of the arrow until the pawl I engages with a tooth, enabling the oscillation of the lever E to rotate the ratchet. The lever B is then allowed to resume its former position,

into which it is lifted by the tension of the spring Q, while the ratchet D-continues to rotate, carrying with it the crank S, which reciprocates the rod M. Thus at every revolution the cone J is pulled down onto the bobbin to compress the cop and is raised again to its former position. When the revolution of the ratchet-wheel is nearly completed, the pawl has once more arrived at the mutilated part D and the apparatus comes to rest. The spring N is provided lest the pressure of the cone 0n the bobbin should become excessive, in which case the spring will extend.

The mechanism described is merely an illustration of the kind necessary for carrying out the system, and other combinations for effecting the same purpose may be substituted for the one shown.

Having thus described the nature of this invention and the best means I know for carrying the same into practical effect, what I claim is An apparatus for compressing cops on their spindles, consisting of a hollow cone J, a sliding piece K carrying the same, a rod M 0011- trolling said sliding piece, a shaft U, a crank thereon connected with said rod M, a ratchetwheel fast on said shaft having a portion without teeth, an oscillating lever E mounted freely on the shaft, a pawl carried by said lever eooperatin g with the ratchet-wheel, means for oscillating said lever, and means for initially moving the ratchet-wheel to make the same responsive to the action of the pawl, substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.
